MAX17497AEVKIT#: 3.3V @ 0.6A, 12V @ 0.3A, 85 ~ 265V in

Summary

The MAX17497A evaluation kit (EV kit) demonstrates the MAX17497A controller IC offline AC-DC flyback converter design and features an integrated step-down regulator. The EV kit circuit uses the MAX17497AATE current-mode fixed-frequency flyback converter in a 16-pin TQFN package with an exposed pad.

The EV kit demonstrates the IC’s cycle-by-cycle current limit, soft-start, and UVLO features optimized for universal offline applications (+85V AC to +265V AC). The EV kit circuit is configured for output voltages of +12V and +3.3V and provides up to 300mA and 600mA of current from the respective outputs.

The transformer secondary +12V output is used as the input source for the IC step-down regulator that provides +3.3V at VOUT2.
